This invention :relates to pistolsfsuch `as animals, of the'type in' Whichfra: captive bolt or rod is used which `is impelledbythe eX- plosion of a cartridge, and Which may be returnediby air compressed by the bolt on its outvvardmovement; The'present inventio'n` comprises a: pistol oi" this type having aslidihg hammer adapted to co-.operate with the meansy for retainingl the barrel inthe vtiring position; rlhe l provisionA Afor retaining fthe'barrelr` inthe iirinopo'sitioii maycom'- prise' af sliding 4is'pringcontrolledy barrelsstop catch which, upon being actuated to release 'the b'a-rrelyis adapte-d tofdisplace the hamfmer into'y a .partially-cocked position;` The .hammer 'niay b'exadaptedgtoco-operate with ai sean adapted :to be actuatedy by aT sliding' t'rigger. The ksean may4 be pivotedto a` sliding spring-Controlled se'ar Abolt'. Tliesea'r 'may be adapted to engagey with a relatively stationary part by virtueof which the hammer is released? .k

Theihandle may be hollow and contains a piston by virtue of Which the barrel may be lubricated.

ln Order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory drawings in Which Fig. l illustratesv in sectional elevationan embodiment oft-the present invention.

The handle p has a horizontal groovealid tongue connection with the frame, and the radapted to co-operate :With a l .shoulder Zgupon the se'ar 7c. l`lWhen, as a reg provide' forY this. the :firing pin y ico frame is at the rear closed `bya dove-tail slide Q which forms the resistance fortlie springs 9'-, m, s respectively controlling' the lbarrel stop catch, the iiring pin bolt, and the sear bolt. This dove-tail slide g' restsV at itsv lower extremity'vupon the handle 0, and said handle is retained in relation to the frame in any suitable manner, as for instancev byv transverse screws or pins.

The barrel 1s formedl With a depending i undercut projection t adapted to :fit within an aperture in the frame', which aperture is Valso undercut, thev said projection and aperture being of forms adapted to. permit of a bayonet or equivalent connection between the barrel and the'frame such that the barrel projection may be passed intothe aperture when the barrel is inclined in relationto the length of the frame, whereas upon the barrel'being `oscillated Vinto alignmentl with the .framethe projection cannot vbe extracted. vThebarlr'el has at or near its rear'extremity] a lcam surface 2 adapted -upon closing'to automatically `retract the barrel stop catch e so vthat the latter 'subsequently falls into `engagement with the recess 8 in the rear face barrel with which litis adapted 'to 3 isf a` cartridge Ycase extractor of' exactly the' form well known in ordinary gun rnan'u'-` facture, comprising a part having 'a 'segmental'notch 4 which engages'with the ,flangey of ther'cartridge' case, this segmental notch 4' c bei'n formed with an vupwardly projecting 26.
